(Original title: World's first virtual rail train available)
Science and Technology Daily News (Reporter Yu Huiyou correspondent Liu Yapeng Hu Xiaoliang) “This is the world's first virtual rail train tailored for the smart track express system. Although it is a giant on the road, it is a flexible 'fat'.†6 On February 2 in Zhuzhou, Hunan Province, Feng Jianghua, chief engineer of the Zhuzhou CSR Zhuzhou Group, said in front of a 31-meter-long green “rub wheel†train.
The Intelligent Track Express System (ART) was first created by CRRC Zhuzhou Electric Locomotive Research Institute Co., Ltd. This is a rail transportation system that uses virtual track following and high-efficiency electric transmission technology, and it is also a brand-new technology form of modern rail trains. It does not require the construction of real orbits, and therefore has the characteristics of short construction period, small investment in infrastructure, and flexible deployment. It is a solution for a new type of mass transit rail transit system that can balance transport capacity with cost.
The debut of the world's first virtual rail train is the ART system's vehicle - an innovative modern urban low-floor tram. The train consists of 3 sections, 31.64 meters long, 2.65 meters wide and 3.4 meters high. The maximum number of passengers is 307. The maximum operating speed is 70 kilometers per hour. Compared with modern trams, the vehicle uses rubber wheels to replace traditional steel wheel rails without the need to lay proprietary tracks. Feng Jianghua introduced that the company's self-developed trajectory follows the intelligent control of technology, while relying on specific signal control technology to restrict the train's movement in the virtual track, the train's safety performance is further improved.
Do not look at the large size of the train, but it is very flexible. The turning radius of the entire train is the same as that of an ordinary bus and is smaller than the width of the bus. It is understood that the minimum turning radius of the train is 15 meters. When the train is running on a curve with a turning radius of 15 meters, the width of the channel of the 12-meter bus is 5.8 meters, and that of the intelligent track express train is 3.83 meters, so it can be used on most urban roads. At the same time, the Zhihao train adopts a double head design similar to that of a high-speed train, eliminating the trouble of turning around.
The train adopts the high-speed railway flexible grouping mode, which can adjust the capacity according to changes in passenger flow, and can be adjusted to 5 sections and so on, which can effectively solve the shortcomings of the passengers with small capacity.
The train is also extremely "economic." Feng Jianghua calculated the account. At present, China's subway construction costs about 400 million yuan -700 million yuan / km, modern tram lines cost about 150 million -200 million yuan / km. With the same capacity as modern tramcars, the ZhiZhou train can be put into operation with simple road reconstruction. The overall line investment is about one-fifth that of modern trams. The service life of intelligent track express trains can reach 25 years, which is 3-4 times of the life of new energy buses. At the same time, the construction cycle of an operating line only takes one year. “Comparing with modern trams, building a 10km route will save at least RMB1billion in trains. It is a tailor-made solution for the remediation of urban diseases.â€
On the same day, the Zhuzhou Municipal Government announced that it will tailor-make the nation’s first intelligent track express system demonstration line for the train. According to the plan, the demonstration line is expected to be put into commercial operation next year.
